Merriam-Webster notes that over time the use of the trademarked term may become so widespread that it becomes the generic name to describe captioning, even to the point that people forget that it was once a trademarked name. It goes on to give the example of heroin, which is describes as follows:
In 1898, the German pharmaceutical company Bayer began marketing heroin—whose name comes from the German word heroisch, meaning “powerful.”
The product was marketed as a cough remedy made from a supposedly non-addictive morphine derivative. It was also used as a cure for morphine addiction—which unfortunately caused large numbers of users to become heroin addicts.
In part because of the growing population of “junkies” (a term that may derive from the fact that some supported their addictions by selling scrap metal), Bayer eventually ceased production and lost its trademark.
